Jules is aboard a submarine studying marine life. She’s trying to find a family of whales and must time when the submarine descends perfectly to find them. Her submarine is 22 feet below sea level and descends at a constant rate of 12 ft. per minute. The submarine must stay no less than 400 ft. below sea level. Let m = the number of minutes. Write an inequality that can be used to find how long the submarine can descend. Then, write the time the submarine can descend.
